Hieff: Enabling Efficient VNF Clusters by Coordinating VNF Scaling and Flow Scheduling
2020 IEEE 39th International Performance Computing and Communications Conference (IPCCC), 2020A cluster of Virtual Network Functions (VNF) can serve massive fluctuating traffic by managing VNF instances and distributing flows. However, how to schedule the flows and manage VNF scaling efficiently in a VNF cluster is still an open question. Existing solutions such as hash based schemes encounter imbalance and passive flow remapping obstacles ...

Securing VNF communication in NFVI
2017 IEEE Conference on Standards for Communications and Networking (CSCN), 2017In a modern telco cloud, network functions are performed by groups of single or interconnected virtual machines (VMs), which form virtualized network functions (VNFs). Securing these VNFs is both important and challenging, since the VNFs might be performing some mission critical operations and exchanging sensitive information among each other.

A Framework Integrating FPGAs in VNF Networks
2021 12th International Conference on Network of the Future (NoF), 2021Future telecommunications networks require more throughput and lower latency. The slowdown of Moore’s Law forces one to think beyond traditional CPU servers to satisfy these needs. FPGAs have been shown to provide exceptional throughput and latency, but they currently lack support for many of the orchestration and reconfiguration tools required by ...

VBaaS: VNF Benchmark-as-a-Service
2015 Fourth European Workshop on Software Defined Networks, 2015When rolling out Network Function Virtualization (NFV) services, resource monitoring becomes a critical task subject to different cost-accuracy tradeoffs depending on whether continuous monitoring or more static infrastructure resource views are taken.

A Deep Learning Approach to VNF Resource Prediction using Correlation between VNFs
2019 IEEE Conference on Network Softwarization (NetSoft), 2019Software-Defined Networking (SDN) and Network Function Virtualization (NFV) greatly facilitate network service management. Specifically, these new network paradigms help manage the network environment dynamically and cost-efficiently. Virtual Network Function (VNF) and Service Function Chaining (SFC) are important aspects of the NFV environment.

Cost as Performance: VNF Placement at the Edge
IEEE Networking Letters, 2021This letter studies the virtualized network function (VNF) placement problem for edge systems, where the edge nodes can provide services that are originally deployed in cloud datacenters. As related to the end-users, edge supports low latency when the energy consumption of edge nodes and end users are the main concerns.

ACM Transactions on Storage, 2017
Modern systems use networks extensively, accessing both services and storage across local and remote networks. Latency is a key performance challenge, and packing multiple small operations into fewer large ones is an effective way to amortize that cost, especially after years of significant improvement in bandwidth but not latency. To this

A green VNFs placement and chaining algorithm
NOMS 2018 - 2018 IEEE/IFIP Network Operations and Management Symposium, 2018This paper proposes an Integer Linear Program (ILP) to address Virtualized Network Function Forwarding Graph (VNF-FG) placement and chaining with Virtualized Network Functions (VNFs) shared across tenants to optimize resource usage and increase provider revenue.

A Pattern for a Virtual Network Function (VNF)
Proceedings of the 14th International Conference on Availability, Reliability and Security, 2019Network Function Virtualization (NFV), produces the functions of the network through virtualization of hardware resources. Different networking components such as firewalls, load balancers, and IDS are provided as a service and rely purely on the cloud, which makes expanding and upgrading the network an easy and fast process.

Challenges Towards Protecting VNF With SGX
Proceedings of the 2018 ACM International Workshop on Security in Software Defined Networks & Network Function Virtualization, 2018Network Function Virtualization (NFV) is an emerging technology to implement network functions in software, which reduces equipment costs (CAPEX) and operational cost (OPEX) through decoupling network functions from network dedicated devices and deploying them on high-volume standard servers and running as virtual instances.
